Preparation method of zirconia ceramic false tooth
The invention relates to preparation of a ceramic 3D printing prosthesis in the field of false tooth repair, and relates to a preparation method of a zirconia ceramic false tooth. The preparation method comprises the following steps: mixing nano zirconia powder, a glass phase material and an organic carrier additive according to a ratio of (50-90): (5-50): (5-10) to obtain ceramic slurry; the ceramic slurry is poured into a plastic or high-temperature wax tube, and a wire material is prepared, so that 3D printing forming is facilitated; printing to obtain a printed piece of the ceramic false tooth; and putting the printed piece into a degreasing furnace, performing degreasing treatment at the temperature of 600-900 DEG C, putting the semi-finished product into a sintering furnace, and performing sintering treatment at the temperature of 1300-1600 DEG C to obtain the finished zirconia ceramic false tooth. And the ceramic slurry used in the preparation process has good formability and flowability, and can fill small pores, so that the high-precision ceramic false tooth is obtained.
本发明涉及义齿修复领域陶瓷3D打印修复体的制备，涉及一种氧化锆陶瓷义齿的制备方法为将纳米氧化锆粉体、玻璃相材料和有机载体添加剂按50‑90∶5‑50∶5‑10的比例混合得到陶瓷浆料；将陶瓷浆料灌入塑料或高温蜡质管中，制成丝材，以便于3D打印成型；打印得到陶瓷义齿的打印件；将打印件放入脱脂炉中，在600‑900℃的温度下进行脱脂处理，将半成品放入烧结炉中，在1300‑1600℃的温度下进行烧结处理，得到氧化锆陶瓷义齿成品、本发明快速、准确地制作出复杂的氧化锆陶瓷义齿，且制备过程中使用的陶瓷浆料具有良好的成型性和流动性，可以填充较小的孔隙，得到高精度的陶瓷义齿。
